System.out.println("No of Account:" + Marry.getnu

Answer 1

Oh see you once again.Amazing,thanks my friend😄

Answer 2

name,no,balance this are your class data members and n,num,t are the parameters of constructor which you have to assign to class data members.

Answer 16

See,there is not enough space to post my program

Answer 17

Do you play wechat?

Answer 18

I know how to do，i can post two part of the program over here

Answer 19

import java.util.Scanner;

class Car{
private String name; private int width; private int height; private int length; private double x; private double y; private double fuel;

Car(String name,int width,int height,int length,double fuel){

this.name=name; this.width=width; this.height=height; this.length=length; this.fuel=fuel;
x=y=0.0;
}

double getX() {return x;}
double getY() {return y;}
double getFuel() {return fuel;}

void putSpec() {
System.out.println("The name of the car : " + name );
System.out.println("The width of the car : " + width +"mm");
System.out.println("The height of the car : " + height + "mm" );
System.out.println("The length of the car : " + length + "mm");
}

boolean move(double dx, double dy) {
double dist = Math.sqrt(dx * dx + dy * dy);
if(dist>fuel)
return false;
else{

fuel-=dist;
x +=dx;
y +=dy;
return true;
} } }
(part 1)

Answer 20

class CarTester{
Scanner stdin =new Scanner(System.in);
System.out.println("Please input the name： "); String name=stdin.next();
System.out.println("Please input the value of width: "); int width=stdin.nextInt();
System.out.println("Please input the value of heigth: "); int height=stdin.nextInt();
System.out.println("Please input the value of length: "); int length=stdin.nextInt();
System.out.println("Please input the value of fuel: "); double fuel=stdin.nextDouble();

Car myCar = new Car(name,width,height,length,fuel);
